What North American Union?

It's not unusual to hear the mention of the Amero as being the unifying unit of currency of the "not being implemented" North American Union. What is unusual is that it was proposed as far back as 1999.
From the Fraser Institute (a Canadian Think Tank);
"The plan for a North American Monetary Union presented in this study is designed to include Canada, the United States, and Mexico. Under the proposed plan, bank notes and coins of the currency (tentatively called the "amero" ) will have "amero" symbols on one side and national emblems on the other to preserve important symbols of national identity."
Isn't that warm and fuzzy letting us keep our "symbols of national identity".

"When the United States joined other international organizations like the IMF, the World Bank, the World Trade Organization, and the North American Free Trade Agreement, the expected economic and political gains appeared to offset the surrender of some national sovereignty."
Gosh just surrender a little bit of your sovereinty and we'll set up a North American Union Bank and to siphon off a little more of your hard earned money and tell you how to spend what's left. But remember, there is no North American Union in the works.
